(01. 126-314) This invention relates to a novel and improved flue adapter designed to fit in a stack accommo dent manner.

a special fitting'for a smokestack, which fitting is unitarily referred to as an adapter, the same having a nipple to slip intoan accommodation collar in the stack and a projecting. scoop-like extension functioning as a. satisfactory union for I I more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the same- Figure 1 is a view partly in section and partly in elevation showing a portion of the smokestack, the flue-pipe from the stove or other equipment and the special adapter fitting which serves as a union between the smokestack and flue.

Figure 2 is a view similar to Figure l, the parts being in section, the flue removed and there being a bucket shown for conveniently trapping the sediment and soot.

Figure 3 is a fragmentary sectional view of the reducing thimble on the stove pipe or flue.

Figure 4 is a perspective view of the adapter I per se showing the overall construction.

The adapter, which is in the form of a fitting or attachment, is denoted by the numeral 5 and is of appropriate material and dimensions and is characterized by a cylindrical nipple or sleeve 6,

terminating in circumferentially spaced outstanding bendable fingers 1. This part is of smaller diameter than the extending end portion 8 and a shoulder is thus defined between the two parts. The extending portion has its upper half cut away with the walls cut down on opposed compound curved lines to define a scoop-like spout 9. The nipple 6 slips into the accommoda- 55 i is regarded as unnecessary,

tion collar, or bushing 10 mounted in the vent in the coacting wall of the stack H. The prongs 'or tongues I are bent laterally to thus hold the parts assembled. The flue or stove pipe is indicated at [2 and has a reducedthimble I3 which slips up into the nipple telescopically in an evi- It will be noticed in Figure 1 that a pivoted keeper latch I4 is provided on the bottom half of the flue and the bill thereof is adapted to engage with a keeper hook [5 on the lower central portion of thetip of the spout. The keeper hook serves tomaintain the parts assembled in telescopic relation as shown in Figure 1. It also serves as a hanger for the bail l6 of thesoot collecting bucket I! as shown in Figure 2. The scoop-like shape of the extension of the adapter provides accessibility andfacilitates coupling and uncoupling of the flue pipe [2.

In practice, it is evident that the adapter 5 is anchored in the collar and held in place by the bendable prongs or tongues 1 and the extension provides a saddle for properly seating the coacting end portion of the stove pipe I2. The thimble [3 projects into the nipple and the shoulders on the respective parts coact in abutting relationship to assist in maintaining the parts assembled. Then they are latched securely together and properly coupled as shown in Figure 1. When The latter serves as a convenient suspension or hanger means. for the bucket l1 and also, its top portion being cut away, facilitates scraping of the dirt and soot by a suitable device (not shown) into the bucket.

The device is simple and expedient, foolproof,

reliable and otherwise susceptible of achieving the desired aims.

It is thought that persons skilled in the art to which the invention relates will beable to obtain a clear understanding of the invention after considering the description in connection with the drawing. Therefore, a more lengthy description Minor changes in the shape, size and fingers adapted to engage the inner edge of the thimble, a shoulder on said section adapted to arrangement of details coming within the field of invention claimed may be resorted to in actual engage the outer edge of said thi mble whereby the section is held against movement, said section also including a cylindrical portion beyond said shoulder, and a semi-cylindrical Stovepipe holding extension projecting from said cylindrical portion.
